The {subequations} environment provided by the amsmath package alters the numbering of equations within it to occur in a sequence such as (1a), (1b), .... This tag is not about general embedding of equations within other equations.

I posted a question earlier,
multiple subequations same line with reference
But I'd like to be able to combine the numbering at the end of the line for the following two cases:
Re = UL/nu , Ha = BL ...

I wonder how environment \subequations is different from \gather. I know the numbering format for the two is a little bit different and you can refer to a single equation in \subequations environment. ...

I have Equations 11, 12, 13 and so on. I want the next equations to be 14a and 14b, but the one after should again be 15, i.e., keep the ordering. I know how to tag equations, but then the equation ...

I am using the subequations environment and observe non-uniform vertical spacing between subequations. Specifically, the space between the first and second equation is larger than the other spaces. ...

How to enumerate two equations that go after a curly brace?
How to make the enumeration use digits and letters, so two equations have number 1.a and 1.b?
\documentclass{article}
\usepackage{amsmath} ...

I'm using the following code to write an article, but I'm having some problems cross-referencing the equations with hyperref.
The \eqref{} code returns the right equation's number. But the hyperlinks ...

For typesetting a mathematical program I use the subequations environment to number the equations. The restrictions are aligned using the alignat environment (see MWE1).
What I would like to achieve ...

I want to align all the terms of two similar subequations, but the problem is that each one is long enough to need breaking. The problem is that after breaking \align tries to align every line with ...

I am trying to reference a set of equations that are placed within a alignat and subequations environments. I would like to reference them as Eq. 1 together, rather than Eqs. 1a and 1b separately. The ...

How to make a hidden reference to an equation, such that \mathtoolsset{showonlyrefs=true} is overridden (assuming it is active)?
Alternatively, how to switch off showonlyrefs temporarily (regardless ...

I work with LaTeX for long time and I used eqnarry. But that's obsolete so I gave equation and aligned a try. The problem is, that if I reference to my equation it shows the chapter numbering (?), but ...

I'm using the subequations environment in a book in which some text is in sans serif font. When I have a reference to a subequation, the reference comes out in a serif font, even if the surrounding ...

I'm trying to make a table containing 4 equations in which the two in the left column are labelled 1a and 1b, and the two in the right column are labelled 2a and 2b.
I've been able to construct such ...

I'm trying to write a list of equations from a chapter of my textbook, each one preceded by a \label{} command so that I can refer to it in the rest of the text.
However after the 1st \begin{align} ...

I want to number sub-items of an array I have in order to refer to the right equation and not to the set of equations (SEE the pictures attached):
Figure that should call 1.35a, 1.35b, 135.c, 1.36a, ...

I am trying to use subequations in a document. Playing around with my preamble I found out that if I use babel and hyperref package at the same time, a fatal error is occured and no .pdf is produced.
